I've been looking at ESRI Shape files and decided to create ShapeToDxf (Windows only). I wanted to see how hard it was and how much of a market there was.
The download is a very early beta, but if you want to make DXF files from your SHP files it could be useful. I don't ask for your email, but I do ask for your feedback!
The back half of ShapeToDxf application Pointor. After a few years of development I know more or less what Pointor users want, but I'm not so sure what Shape To Dxf should deliver, especially as far as 3D and layers and text annotations etc. are concerned.
Anybody who gives me feedback, good or bad, will get the final release free (if they want it!)
